During 750 HBO sessions, the dynamics of cardiovascular and respiratory system indicators in patients before and after each session was studied. The data of computed tomography (CT) and external respiration function (FVD) were analyzed before and after the course application of the hyperbaric oxygenation method. The contingent of subjects: 65 patients of different age groups who had suffered a coronavirus infection of varying severity were treated and examined.Results and their discussion. Hyperbaric oxygenation in the complex treatment and rehabilitation of postcovid syndrome is an effective and promising technique. An algorithm for conducting the HBO course at the outpatient stage of rehabilitation has been developed. The use of the method at an earlier time after hospitalization helps to solve not only medical problems faster — the restoration of functions and structures of damaged organs, but also social problems — the return of able-bodied patients to work and normal daily loads.","PeriodicalId":175902,"journal":{"name":"Marine Medicine","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134486741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A gas environment with an oxygen content of 17–16% vol., Nitrogen — the rest, at normal barometric pressure and other microclimate parameters was maintained in the test bench. The duration of the bench tests was 60 consecutive days, during which the volunteers were kept in a hypoxic environment for 4 hours every day. Resistance to hypoxia was assessed using tests with breath-holding during inhalation and exhalation.Results: in the course of the research, the fact of a decrease in the human tolerance of transient hypoxia when in specified hypoxic environments was revealed.

Breathing with a heated oxygen-nitrogen mixture consisted in an increase (by approximately 25–35%) of the values of the integral indicator of microcirculation against the background of a decrease in its efficiency. Switching to breathing with a heated helium-oxygen mixture «HeliOx 25/75» in all examined persons also led to an increase in the volumetric velocity of the peripheral blood flow. However, the degree of increase in the indicator (by 35–45% compared with normal breathing conditions) turned out to be significantly more pronounced than it was during breathing with a heated oxygen-nitrogen mixture. In addition, when breathing «HeliOx 25/75», starting from about the 2nd minute of breathing, an increase in the efficiency of microcirculation was observed due to an increase in the «contribution» to the blood flow reaction of its «active» (neuromyogenic) components.","PeriodicalId":175902,"journal":{"name":"Marine Medicine","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127951995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the frequency of occurrence of cardiovascular risk factors and the course of arterial hypertension in military personnel in the Arctic region.Materials and methods. 251 male servicemen aged 23–44 years (mean age 33.7±4.9 years) were examined and studied medical records. Depending on the place of service, all the examined were divided into two groups: I — 159 military personnel serving in the Arctic, II — 92 military personnel from the Western Military District. The studied cardiovascular risk factors included dyslipidemia, tobacco smoking, high blood pressure, abdominal obesity, psychosocial factors, dietary disorders, regular alcohol consumption, physical inactivity. We also analyzed the frequency of occurrence of a confirmed diagnosis of neurocirculatory asthenia and stage I–II hypertension.Results and its discussion. The survey showed a significant increase in the incidence of most of the studied predictors of cardiovascular risk (dyslipidemia, smoking, negative psychosocial factors, dietary disorders, and regular alcohol consumption) in the Arctic region group compared to the temperate climate group. This is realized in the form of a higher incidence of arterial hypertension and a trend towards an increase in the number of cases of generalized atherosclerosis among military personnel in the Arctic. The data obtained may indicate the need for a more thorough selection for service in the Arctic region with a mandatory in-depth examination of the circulatory and metabolic systems, including electrocardiography, echocardiography, stress treadmill test, ultrasound examination of the brachiocephalic arteries with the determination of the thickness of the intima-media complex, sphygmomanometry with the determination of the stiffness and biological age of the vessels, the study of the lipid profile and fasting glycemia. It is advisable to conduct an annual examination of the military personnel of the Arctic group at the place of service with the involvement of visiting military medical commissions, which should include a cardiologist and a specialist in functional diagnostics.","PeriodicalId":175902,"journal":{"name":"Marine Medicine","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123295065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
